[2.0] System.Net.Mail.Attachment.Add is only working in Debug Mode??

am using .NET 2.0 Visual Studio 2005 using C#.

I'm attaching files using System.Net.Mail.Attachment.Add(...)
My problem is, that this is working fine, when I'm debugging with visual studio.
but in Livemode the file-attachments seems not to work. (no error is thrown but I don't get the mail)

Calling the site via localhost also sends no mail.
Sending Mails using this System.Net.Mail-Class always works fine (without attachments).

Please help!!

here is the code

c# Code:

xxxxxxxxxxxxxxxxxxxxxxxx
 
public void sendmail(string frm, string to, string bcc, string cc, string sub, string bdy, string smtpserver, string smtpusername, string smtppassword)
 
{
 
int fileLen=0;
 
string pathAndFile = "";
 
try
 
{
 
if (smtpusername != "" && smtppassword != "")
 
{
 
System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage(frm, to, sub, bdy);
 
if (bcc != "")
 
msg.Bcc.Add(bcc);
 
if (cc != "")
 
msg.CC.Add(cc); 
 
if (txtFileUpload.HasFile)
 
{
 
pathAndFile = txtFileUpload.PostedFile.FileName;
 
fileLen = (txtFileUpload.PostedFile.ContentLength / 1000);
 
if (fileLen > 500)
 
{
 
CreateMessageAlert(this, "Maximum File Size Limit is 500 kbps", "alert", "MyMessages.aspx?link=3");
 
return;
 
}
 
System.Net.Mail.Attachment attachment = new System.Net.Mail.Attachment(pathAndFile);
 
msg.Attachments.Add(attachment);
 
 
}
 
msg.IsBodyHtml = true;
 
System.Net.Mail.SmtpClient smtpClient = new System.Net.Mail.SmtpClient(smtpserver);
 
smtpClient.UseDefaultCredentials = false;
 
smtpClient.Credentials = new System.Net.NetworkCredential(smtpusername, smtppassword);
 
smtpClient.Send(msg);
 
if (pathAndFile != "")
 
{
 
msg.Attachments.Dispose();
 
}
 
 
}
 
else
 
{
 
System.Web.Mail.MailMessage msg = new System.Web.Mail.MailMessage();
 
msg.From = frm;
 
msg.To = to;
 
msg.Bcc = bcc;
 
msg.Cc = cc;
 
msg.Subject = sub;
 
if (pathAndFile!="")
 
{
 
msg.Attachments.Add(new MailAttachment(pathAndFile));
 
}
 
msg.BodyFormat = MailFormat.Html;
 
msg.Body = bdy;
 
SmtpMail.SmtpServer = smtpserver;
 
SmtpMail.Send(msg);
 
if (pathAndFile != "")
 
{
 
msg.Attachments.Clear();
 
// msg.Attachments.Dispose();
 
}
 
}
 
}
 
catch 
 
{}
 
}
 
sendmail(Session["userid"].ToString(), email, tempbcc, tempcc, txtSubject.Text, body, smtpserver, smtpusername, smtppassword);

Hmm, you say no email arrives but there isn't an "error". I beg to differ. You never, ever use empty catch blocks as you have in lines 121 through 123 of your sample.

Code:

---

catch
{}

---

Out of interest - kbps is "kilobits per second"; it doesn't make sense to use this as a file size limit.

i agree with axion, your code should not have run in the first place, your catch should contain somthing like:

catch (Exception ex) { <imo this can be left empty but for user-friendliness always try and inform the user that there is an error...> };

If you remove the try-catch block. what exception do you get?
